The Finite-volumE Sea ice–Ocean Model (FESOM2) [PDF]
Geoscientific Model Development, 2017 Version 2 of the unstructured-mesh Finite-Element Sea ice–Ocean circulation Model (FESOM) is presented. It builds upon FESOM1.4 (Wang et al., 2014) but differs by its dynamical core (finite volumes instead of finite elements), and is formulated using the
